Hi Janis,
A new 20021003 Blitz snapshot was created and is available
on the Blitz website. This should suit your gcc testing needs.
Thanks for reporting the two minor problems you noted. We can
certainly fix those things. I've seen the problem with the
runtime libraries, although it seems to depend on the options
used when building and installing gcc.
Also, perhaps we can get some feedback from you on gcc compiler
options. First, has the default template depth parameter in gcc
changed recently? We used to add -ftemplate-depth-30 to blitz
compiles to avoid failures with some codes. But now it seems that
this setting is lower than the current default value and is causing
other codes to fail to compile with gcc 3.2. Second, is the flag
-fstrict-aliasing on by default with -O? Third, is the -fno-gcse
flag still needed when compiling the sort of expression templates
code that blitz uses? Thanks in advance for any info you can give
on these compiler issues.
Regards, Julian C.
